Effective date: March 15, 2026

1. Agreement to Terms

By accessing or using Engineering Database at engDatabase.com (“Service”), you agree to be bound by these Terms of Service (“Terms”). If you do not agree, do not use the Service.

The Service is operated by engDatabase.com (“we,” “us,” or “our”). We reserve the right to update these Terms at any time. Continued use after changes constitutes acceptance of the revised Terms.

2. Description of Service

Engineering Database provides searchable access to engineering reference data across structural, mechanical, electrical, civil, chemical, and aerospace domains. The Service supports natural-language and structured queries against our reference table catalog.

3. Engineering Data Disclaimer

Important

All data provided through this Service is for reference purposes only. It is not a substitute for professional engineering judgment, licensed design work, or verification against primary sources (AISC, ASME, ASHRAE, NEC, ACI, or other governing standards and codes).

You are solely responsible for verifying the accuracy, applicability, and completeness of any data retrieved through the Service before using it in any engineering analysis, design, construction, or decision-making process. We make no representation that the data is error-free, current, or suitable for any particular application.

The Service does not provide engineering advice and does not replace the services of a licensed professional engineer.

4. Accounts and Registration

To access the Service beyond the free tier, you must create an account by providing a valid email address and password. You are responsible for maintaining the confidentiality of your account credentials and for all activity that occurs under your account.

You agree to provide accurate information during registration and to notify us immediately of any unauthorized use of your account.

5. Subscription Plans and Billing

The Service offers the following tiers:

  • Free — 20 searches/month, no cost.
  • Engineer — 100 searches/day, unlimited monthly, $40/month.
  • Professional — 1,000 searches/day, unlimited monthly, $100/month.
  • Enterprise — Unlimited searches, custom pricing.

Paid subscriptions are billed monthly through Stripe. By subscribing, you authorize recurring charges to your selected payment method. You may cancel at any time; cancellation takes effect at the end of the current billing period. We do not provide prorated refunds for partial billing periods.

We reserve the right to modify pricing with 30 days’ advance notice. Price changes will not apply to the current billing period.

Non-search endpoints (schema browsing, table catalog, unit lookups) are free across all tiers and are subject only to general rate limits.

6. Acceptable Use

You agree not to:

  • Attempt to scrape, bulk-download, or systematically extract the contents of our reference tables.
  • Circumvent rate limits, usage quotas, or any access controls.
  • Reverse-engineer, decompile, or attempt to extract the source code or underlying search algorithms of the Service.
  • Use the Service to build a competing product or dataset.
  • Share account credentials or allow multiple users to access a single account (except under Enterprise agreements).
  • Use automated tools, bots, or scripts to access the Service beyond documented API usage.

We reserve the right to suspend or terminate accounts that violate these terms, with or without notice.

7. Intellectual Property

The Service, including its search engine, table schemas, data curation, user interface, and documentation, is the proprietary property of engDatabase.com and is protected by applicable intellectual property laws.

Engineering reference data served through the Service is curated from publicly available standards and references. Individual data points (e.g., a steel section’s moment of inertia) are factual and not subject to copyright. However, the curated collection, schema design, search infrastructure, and presentation are proprietary.

8. Limitation of Liability

To the maximum extent permitted by law, engDatabase.com shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of the Service, including but not limited to damages resulting from reliance on data obtained through the Service.

Our total aggregate liability for any claims arising from or related to the Service shall not exceed the amount you paid us in the twelve (12) months preceding the claim.

9. Disclaimer of Warranties

The Service is provided “as is” and “as available” without warranties of any kind, whether express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, accuracy, or non-infringement.

We do not warrant that the Service will be uninterrupted, error-free, or that any data will be accurate or complete.

10. Termination

You may terminate your account at any time by contacting us or through the account settings. We may terminate or suspend your access at our discretion for violation of these Terms or for any other reason with reasonable notice, except in cases of egregious violations where immediate termination may be necessary.

Upon termination, your right to use the Service ceases immediately. Sections 3, 7, 8, 9, and 11 survive termination.

11. Governing Law

These Terms shall be governed by and construed in accordance with the laws of the State of Oregon, United States, without regard to conflict of law provisions.
